The radius of the base of a cylinder is increasing at a rate of 11 meter per hour and the height of the cylinder is decreasing a

musickatia [10]

Answer:

The volume of the cylinder is decreasing at a rate of 83629.2 m³/h.

Step-by-step explanation:

The volume of a is given by:

$V = \pi r^{2}h$

Where:

r: is the radius = 55 m

h: is the height = 88 m

We can express the rate of change of the volume of the cylinder as follows:

$\frac{dV}{dt} = \pi[h\frac{2rdr}{dt} + r^{2}\frac{dh}{dt}]$

If dr/dt = 11 m/h and dh/dt = -44m/h, we have:

$\frac{dV}{dt} = \pi[88 m*2*55 m*11 m/h + (55 m)^{2}*(-44 m/h)] = -83629.2 m^{3}/h$

Therefore, the volume of the cylinder is decreasing at a rate of 83629.2 m³/h.

I hope it helps you!

A group of 5 hippos at the zoo eats a total of 2,100 pounds of food each

wolverine [178]

First, divide the total pounds of food eaten by 7 (7 days in a week).

2,100/7 = 300 pounds

Then divide this quotient by the 5 hippos.

300/5 = 60 pounds

Therefore, each hippo eats 60 pounds of food every day.
